I'm trying to change the '+' key on my Harmony One remote to equate to the '-' key on a DirecTV remote for an HR24-200 DVR. I have gone through the Learn Infrared Commands step in the Device Options part of the device setup. When doing so, I receive confirmation that the key was recognized.
I have also done the Customize Buttons step in the Device Options setup to assign the '+' to the '-' from the dropdown list. I have updated my remote.
I had successfully assigned this key on my previous DVR but cannot seem to do so on this one. Any thoughts?
